IMPROVEMENT IN STEAM-CONDENSERS.

Specification forming part of Letters Patent No. 124,065, dated February27, 1872.

Specification describing a new and Improved SteamCondenser andWater-Filter, invented by ARCHIBALD KENNEDY and JOHN H. BERK- SHIRE, ofMuscatine, in the county of Muscatine and State of Iowa.

The invention will first be fully described and then clearly pointed outin the claim.

Figure l is a sectional elevation of our improved condenser and filtertaken on the line 00 .r of Fig. 2, and Fig. 2 is a horizontal sectiontaken on the line y y of Fi 1.

bimilar letters of reference indicate corresponding parts.

A is a vertical vessel, of sheet metal, preferably with conical ends, inthe upper part of which is a perfo *ated sheet-metal distributer, B, ofany suitable kind, into which the exhaust steam is discharged from thecylinder to be distributed into spray or jets as much as possible, andabove this is the mouth of a cold WiltLT-Sl11')1)ly1)lp6, D, dischargingupon it in a manner calculated to condense the steam as much aspossible. Below the pan B is a diaphragm, E, which conducts the water tothe long pipe 1, extending to the mud-well G,

- where the mud is deposited, while the water rises up through the spaceH and filters I K to the clear-water space L, from which it is taken bya pipe, M, to the feed-pump. N is an escapepipe for the surplus water. 0is avalve in the bottom of the mud-well, which is to be lifted from timeto time by a lever, P, to allow the mud to escape and to clear thefilters, by allowing the water in chamber L to flow back and wash offthe collections upon the ends and sides of said filters. Q representsman-hole covers, which are placed over holes formed in the side of thevessel A for packing the filters.

This apparatus is calculated to be very effi-. cient in condensing thesteam; also in heating and purifying the feed-water. It is also veryuseful as a filter alone for purifying cold water for the supply ofrailroadtanks for fill ing the tenders.

The particular advantage of the perforated steam-receiver and spreaderBunder the waterspout D consists in distributing the exhaust steam morefreely without those sudden puii's at the commencement of the exhaust.We also claim that the receiver and spreader eases the first injectionof the exhaust from the cylinder (by the operation of condensation) andameliorates the exhaust, and at the same time more thoroughly bringsinto contact and heats the falling water and in conjunction with thepartially-perforated rings and the angular flange projecting downwardoutside of said ring, prevents the falling water from being forced upthe escape-pipe, whereby the outward escape is made more easy and even,and is more thoroughl y brought into contact with the cold water than itwould be were the steam exhausted directly through an open-mouthed pipeinto the heater.

By confining the steam we did not mean to imply that the steam should hesent back, or should increase the pressure upon the engine; but shouldbe more easily absorbedby the cold water shower.

Our device does not require cleaning or repacking more than once in tenweeks, while all others we have seen require cleaning once a week.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- The combination, in vessel A, of water-spout Dand steam-distributer B, as and for the purpose described.
